Project: Accelerating Uproot with AwkwardForth

Uproot is a Python library made for ROOT I/O. Uproot can only read columnar data quickly. The record-oriented layouts are hundreds of times slower, hence, in this project we aim to accelerate Uproot using AwkwardForth, a Domain Specific Language. This fellowship will involve writing up a meta-programming solution to generate schema-specific AwkwardForth code to read ROOT files. This project will result in a fully functional ROOT format reader that can replace the current solution and also outperform it.
